NUT-LOCK.

SPECIFICATION forming part of Letters Patent No, 294,900, dated March 11, 1884.

I Application filed December 6, 1853. (No model.)

To @ZZ whom it may ooncern Be it known that I, W'ILLIs L. MOORE, a citizen of the United States, residing at Rochester, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon', which form a part of this specification.

My vinvention relates .to improvements in nut-locks.

The object of my invention is to provide a strong and enduring but inexpensive device of such material and size that it will 'not soon rust out or be destroyed by exposure to the weather, and of such structure as not likely to be broken by severe shocks, sudden strain, or other rough usage, andl when applied and properly adjusted will permanently lock and hold the nuts to which it is applied in position on their bolts, and which also is capable of beingremoved and reapplied without injury to its structure or destroying its functional capability. How I attain these objects is explained herein, and by reference to the accompanying drawings, and to the letters mark ed thereon, which are hereby made a part of this specification. Y

Figure 1 is a perspective View of my invention applied to nuts on the bolts in a fish-,plate of a railway-rail. of the locking-plate in act of being applied to nuts on bolts in a fish-plate. Fig. 3 isa perspective View of the locking-plate.

Like parts are represented by the same reference-letters in the several views.

Referring to the drawings, .A represents the locking-plate, made of heavy iron or other suitable material, and entirely inelastic, provided at one end with a slot, B, and jaws C, adapted to pass beneath the nut and on either side of the nut-carrying bolt, and to extend out to and flush with the outer edge of the nut,

and having a shoulder, D, at right angles to the face of the plate, adapted to come in contact with and engage the inner edge of the Fig. 2 is a perspective ViewV nut, the locking-plate Abeing of such length, and the end E being of such width and so cut off diagonally as to form an acute angle at E', that thelocking-plate will when being applied, partially pass by the nut G, and being supported in that position, as provided for, the point E will lie against the nut G, as hereinafter described.

F and G are two nuts to be locked.

H is the part of a sh-plate affixed to the 6o end of the railway-rail I, and K is the lower iiange of the rail.

The mode of applying my nut-lock is as fol- 1lows: The fish-plate H being placed on the rail I, in the ordinary way for fastening rails 6 5 together, and the bolts put in position through the rail and fish-plate, the nut G is put onto its bolt and screwed down tightly to its place, having its edges square with the fish-platew that is, as nearly vertical and horizontal as 7o possible. The nut F is then put on its bolt and screwed downvso far that the jaws G of the locking-plate A will barely pass beneath it, in a vertical or other position, not more than one-half a turn from its seat, but so that 7 5 the shoulder D will' come squarely against and engage the side of the nut F, asshown in Fig. 2. The nut Fis then screwed tightly down, the locking-plate being swung over to the right, the shoulder D remaining firmly against the edge of, and the jaws G beneath, and all moving with the nut .F until the end E of the n v locking-plate partially passes the nut G, and the lower edge of the plate rests against the lower ange, K, of the rail I, or other suitable support, and the upper and outer corner, E', of the locking-plate is at and against the middle of the edge of the nut G, and thereupon, the nut G being unscrewed by the part of a revolution sufficient to strike against and hold the end E of the locking-plate down to place,

both nuts F and G are permanently locked, and cannot loosen, except by first tightening the nut G with awrench or other suitable ap- A plia-nce.

`I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. In a nut-lock, a rigid non-elastic lockingplate provided withv slot, jaws, and shoulder ioo at one end, the jaws being` adapted to pass beneath the nut and on either side of the nutearrying bolt, the shoulder being adapted to iit against and engage the nut, and at the other extremity being adapted to partially pass by and lie against and hold in position a second nut at an adjusted distance from the tirstnut, thereby looking` both said nuts, said lookingplate being capable of being removed and reapplied, either in the same place or elsewhere, without change or injury to its forni or structure, substantially as and for the purpose set forth.

2. The non-elastic locking-plate A, having a slot, B, and jaws C, adapted to pass'beneath 15 the nut F and 011 either side of the bolt which carries nut F, the shoulder D, adapted to it against and engage the nut F, and the end E, in combination with the nuts F and G, the shplat-e H, and the rail I, with its lower flange, K, all substantially as and for .the purpose speeied.

In testimony whereofI I at'tix my signature in presence of two witnesses.
